I discovered that wpa_supplicant is running on some of my CentOS 6.4 servers, without having been explicitly declared in the chkconfig setup. What can be causing this ?

$ chkconfig --list | grep wpa_supplicant
wpa_supplicant  0:off   1:off   2:off   3:off   4:off   5:off   6:off
$ pgrep -l wpa
1767 wpa_supplicant

NetworkManager will run it.

See here. It may be installed by default, or can be pulled in as a dependency if you installed a desktop (Gnome, KDE, etc.)
